LS-DYNA (GRAVITY LOADING)

If the draw type is set to GRAVITY (TOOLS/ANALYSIS SETUP/DRAW TYPE), the Analysis dialog box illustrated in Figure 15.3.1 is displayed when clicking LS-DYNA. Refer to 11.1  Analysis Setup for detailed description about the setup of draw type. There are three methods provided here to solve the gravity loading: Explicit (Dynamic Relaxation), Implicit (Dynamic) and Implicit (Static). The Implicit (Static) method is recommended. When the Implicit (Static) method is selected, the solver will be defaulted to be double precision. Once the solver method is selected, the user can click Implicit Parameters (or Dynamic Relaxation) button to set the relevant parameters.
